The preferred embodiment relates to a base structure for a ball court, particularly a squash court, with a supporting structure resting on a building base or the like and a floor forming a playing surface resting on the supporting structure, as well as a safety glass pane for forming such a base structure.
Known ball courts, particularly squash courts, have base structures of this type with a playing surface, in which an elastic parquet or laminate floor is located on a supporting structure resting on a building base or the like. The elastic structure of the parquet floor gives the playing surface playing characteristics considered pleasant by the player.
However, such base structures can only be used if the base structure is protected against influences of the weather, particularly rain. It has been found that the known base structure is also not completely satisfactory with regards to its antislip characteristics.
It is an object to provide a base structure in which antislip characteristics are improved and which can be played on virtually throughout the year even when there is an unreliable or completely lacking protection against rain.
The base structure for a ball court, particularly a squash court, has a supporting structure resting on a base and a floor forming a playing surface resting on the supporting structure. The floor comprises a plurality of safety glass panes laid side-by-side and which are freely vertically movable relative to one another and whose surface forming the playing surface is provided with a plurality of rough areas. The supporting structure has an elastic overlay for the safety glass panes.
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the preferred embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, and such alterations and further modifications in the illustrated device and such further applications of the principles of the invention as illustrated as would normally occur to one skilled in the art to which the invention relates are included.
The preferred embodiment provides a safety glass pane, which can be used for the equipping of a base structure according to the preferred embodiment in a manner to be described hereinafter.
In a base structure of the aforementioned type, the preferred embodiment solves the problem in a further development in that the floor is formed by a plurality of safety glass panes laid in a substantially jointless manner with abutting lateral edges and which are freely vertically movable relative to one another and whose surface forming the playing surface is provided with a plurality of rough areas, and that the supporting structure has an elastic overlay for the safety glass panes.
The safety glass panes can have a rectangular shape.
The safety glass panes can also have a square shape.
In a further variation the elastic overlay comprises a flexible foam and/or rubber layer.
It is also possible for the elastic overlay to be formed by a plurality of soft foam and/or rubber pads.
It is also possible to provide between the elastic overlay and the safety glass panes a lighting device for the selective rendering visible of marking lines, advertisements and/or impact surfaces.
According to another variation, the safety glass panes are backed on their underside remote from the playing surface with a colored film or the like.
The preferred embodiment also proposes a safety glass pane for equipping or forming a base structure for ball courts, particularly squash courts, which is characterized in that the safety glass pane is constructed as a laminated safety glass pane.
The laminated safety glass pane can have at least two individual silicate glass panes interconnected by means of a laminate plastic film.
It is also possible for at least one of the individual glass panes of the laminated safety glass panes to be constructed as tempered glass panes.
In a further variation the two individual panes of the laminated safety glass pane can in each case have a thickness of 4.0 to 6.0 mm, while the laminated plastic film has a thickness of 1.5 to 2.5 mm.
It is also possible for the thickness of the two individual panes of the laminated safety glass pane to in each case have a thickness of approximately 5.0 mm and for the laminated plastic film to have a thickness of approximately 2.0 mm.
The safety glass pane surface facing the playing surface can also be multiply etched.
In a further variation the rough areas are formed by ceramic colored dots applied in the screen printing process and subsequently fixed on and which have a substantially circular disk shape.
The ceramic dots can have a diameter of 1.5 to 2.5 mm and cover approximately 50% of the safety glass pane surface.
The preferred embodiment is based on the surprising finding that it is possible to create a high quality base structure for squash courts by moving away from the laminate or parquet floor principle previously considered absolutely necessary. In place of this use is made of glass panes, which in conjunction with the correspondingly designed supporting structure have the necessary elasticity, but can be given an antislip finish on the surface thereof by ceramic dots, which are preferably applied in the screen printing process, followed by firing on. The glass pane construction of the floor structure of the preferred embodiment offers the possibility of using corresponding lighting devices to create coloring and marking effects of a random nature, so that it is e.g. unnecessary to have the normally raised marking lines on the playing surface, which significantly increases safety for players.
Moreover, the lighting devices of the aforementioned type, for which naturally the transparency of the safety glass panes used according to the preferred embodiment is of decisive importance, offer the possibility of the corresponding marking of impact surfaces or the like by the umpire.
In the embodiment shown in
The ceramic dots 12 shown in greater detail in
As shown in
The surface, at the top in
In the case of the base structure shown in
The surface area of the complete squash court is 62.5 m2 and for this use is made of 16 identically sized, square safety glass panes 10. The playing surface is 9.75 m long and 6.40 m wide. The base structure generally has a thickness between 7.0 cm and 8.0 cm. If the building base is uneven, this can, for example, be smoothed with quartz silicate. The Styrodur layer preferably has a thickness of approximately 4.0 cm. The preferably roughly 20.0 mm thick flexible foam or rubber layer 16 can be covered with a colored carpet or film 14, as a function of which surface of the safety glass panes 10 is to be visible to the observer. On the film can be laid 16 large safety glass panes with dimensions 1.6 m×2.43 m.
In the preferred embodiment although the safety glass panes are laid in a substantially jointless, abutting manner, they are not connected at their lateral edges, so that there can be an individual height displacement thereof. In conjunction with the elasticity of the substrate, this leads to an excellent elasticity of the playing surfaces, which is gladly accepted by players.
The features of the preferred embodiment disclosed in the description and drawings can be in random combination for the implementation of the different embodiments.
Many other alternatives are envisioned. By way of example only, the following is noted. Although the base structure has been described for a squash court, other types of ball courts may make use of the base structure described herein. The dots may be placed on the safety glass panes may be formed thereon with a variety of techniques. The carpet layer may or may not be employed, although it is preferred. Although rubber or foam is described for the flexible or elastic layer 16, other materials may be employed. Similarly although it is preferred to use a Styrodur layer at 18, other types of supporting layers may be employed. Also the layer 18 may not necessarily rest on a building base but may rest on any type of base. Although the safety glass panes have been described as comprising two individual panes, other constructions may be employed for the safety glass panes. Although the glass panes have been shown to be square, they may have other geometric shapes. Although the panes are preferably laid in close abutting proximity to each others they could also be spaced apart with perhaps a material strip laid therebetween.
While a preferred embodiment has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention both now or in the future are desired to be protected.
